mounted to turn cylindrical abutmentsG, eX- tending into the working' chamber C and in frictional contact with the rotor B, the said abutinents G being preferably one less in 6o number than the number of heads B on the rotor B. Each of the abutments G is pro vided on its peripheral face with a cut-out portion G for the passage ci" the rotorlheads B. On the shafts Gr2 ofthe ahutn'ientsqG are 65 secured pii'iions H/ in mesh with a gear-wheel H', attached to the 'rotor-shaft D and extending within the exhaust-chest F. W hen the rotor B and its shaft D are rotated, then the4 'gear-wheel H and the pinions H impart a ro- 7o tary motion to the abut'rnents G to rotate the abiitinents and the rotor B at the saine pe ripheral speed, it being understood that the rotor-heads B register successively with the cut-out portions G ofthe abutments G to al- 7 5 low `the rotor-heads to pass trom one side of the abutments'to the other' side thereof.

into the working chamber C open sets of admission-ports ay a', arranged in the wall of the cylinder A on opposite sides of the re- 30 cesses A3, containing theabutrnents G, so

'that the live motive agent can be admitted to either side of an abutment with a View to run the engine either in a forward of a backward direction. agent passes through the port a into the working chamber C and acts on the pistonheads B oi the rotor B then the latter is rotated in the direction oi the arrow (s ee Fig.

l;) but when the motive agent passes into 90 the working chamber C by way oi the ort a then the rotor B is rotated in the inve se direction ot the arrow The ports (L and ci are adapted to register with ports l) b, (see Figs. 5 and 6,) formed in the reversing-valve 95 v i, mounted to turn in the stearnchest E, and

Ythe said ports Ii b are adapted to register with elongated openings c, formed in the rim J of the adinissioi'irvalve J, secured on the rotor-shaft D and likewise extending in the 100 steani-cliest E. The openings c are adapted to register with ports d, formed in the rim .-K

i the cut-off valve K, mounted to rotate loosely on the rotor-shaft D and likewise extending witliin the steaiii-cliest E. oil` valve K forms with the admission-valve J an annular chamber li, connected by apertures e, formed in tlie web ol the valve K with the interior or" the steam-chest E, so that the live motive opening. to the chamber L and from the latter .Jay et the port d opeinngsc Thus when the motive 85 The cut- 05 entcan pass by way of the said I IO into the ports b b and from the latter into either of the ports 'a a', according to which of the sets of ports a b or a b is in register at the time. Thus when the' several parts are in the position shown in Fig. 6 the ports b and a are connected with each other, while the ports b and a are out of register, and hence the live motive avent passes .through the ports b-and a into he working chamber C to cause the rotor B to rotate in the direction of the arrow When the reversing-valve I is turned to move the ports b and a out of revister with each other and the ports b an a into register with each other, then the live motive agent passes into the working chamber C to cause the rotor B to travel in the inverse direction of the arrow of the cut-oil valve K is secured or formed a bevel gear-wheel K3, (see Fi 5,) in mesh with a bevel-pinion K3, secure on a shaft K4,

" extending transversely and j ournaled in suit- 4able bearings arran ed o n the steam-chest E.

0n the outer end o the shaft K4 is secured a handle K5, adapted to be taken hold of by the operator for turning the shaft K4 and pinion K3 with a view to rotate the bevel gearwheel K2, and consequently the cut-ofiI valve K, to bring the ports d sooner or later in register with the openings c in the admissionvalve J to cut oil the motive agent correspondin ly sooner or later. On the handle K5 is fu crumed a hand-lever K3, carryinor a locking-pin K7, adapted to enga e one o a series of apertures in a segment 3, attached to the steam-chest E, so as to lock the handle K5, and conseqi-iently the shaft K4, after the cut-off valve has been moved into the desired cut-0H position.

In order to reverse the engine, the reversing-valve I is turned, and for this purpose the reversing-valve is provided at its fieripheral face wit a segmental gear-wheel in mesh with a segmental pinion I2, secured on a shaft I3, carrying at o ne outer end a handle I4, provided with a spring-pressed hand-lever I5, controlling a locking-pin I, adapted to -enoage a notched segment I7 to lock the handle 4, and consequently the shaft I3, in the desired position. The shaft I3 extends lon itudinally in the steam-chest E, the cylin er A, cylinder-heads A A2, and the exhaustchest F, (see Fig. 2,) and this shaft I3 also controls the exhaust-valve N, interposed between the head A2 on the cylinder A and its rotor Band arranged in the form of a disk mounted to turn loosely on the shaft D. 'The exhaust-valve N is rovided with sets of ports ff', adapted to registerwith ports gg,formed in the wall ofthe cylinder A and opening into the Working chamber C on opposite sides of the corresponding abutments G. The ports g g are in transverse alinement with the admission-ports a a', as plainlyillustrated in Fig. 3, but are not in communlcation with each other. The ports f are adapted to Onthe face register with ports h h', formed in the cylinder-head A2 and opening into the exhaustchest4 F, from which the exhaust-steam can pass to a suitable place oi discharge by way of an exhaust-pipe F. On the peripheral face of the exhaust-valve N (see Fi 8).are formed gear-teeth N', in mesh wit a segmental pinion I3, secured on the shaft I3, so

that when the latter is turned the said pinion I3 turns the exhaust-valve N to bring either set of ports f or f in register with the' corresponding set of ports g or g.

From the `foregoing it will be seen that when the reversing-'valve I is turned by the operator manipulating the handle I1L the exhaust-valve N turns with it. Now when the ports a and b arer in register and thc ports a and b are out of register the ports f and gare out of register, while the ports f and g are in register, and when the valves I and N lare simultaneously reversed then the ports a and b and the ports f and g move into register, while the ports a and b and the ports j and y move out. of register, In other words, the live steam passes into the lworking chamber C at one side of an abutment G and escapes or exhausts Jfrom the working chamber C at the other side of the same abutment.

The operation is as follows: When the several parts are inthe position illustrated in the drawings and the Orts a and b and f and g are in register witli eachother, then the live motive agent passes Ainto the Working chamber C by way ofthe port a to act on the heads B and thereby turn the rotor B in the direction of the arrow x. Bl setting the cutoil" valve K steam may be a mitted sooner or later to the elongated openings c, and consequently more or ,less steam passes intothe working chamber C during the time the head B travels from one abutmentG to the next following one, it bein understood that af- IOO ter the steam is cut o it works expansively v against the corresponding piston head B', and when the latter has passed the next following port g the steam `exhausts from the working chamber in the rear of the head B by way of the ports g f h into the exhaustchest F. Now by havin one more pistonhead B than abutment's u it is evident that always one ofthe heads B is acted on by the live motive agent under initial pressure, and hence a uniform powerful rotation is given to the rotor Band its shaft'D, used for transmitting the rotary motion of the engine to other machinery. l

By arranging the reversing-valve I and the cut-oi valve K in the steam-chest E at one side of the cylinder A and its head A and having the exhaust-valve N arranged on the opposite side of the cylinder a very compact machine is produced, and convenient access can be had at any time to the said parts by removing either chest E or F.
